(Cl. lf2- 36) This invention relates to shoe presses for pressing soles against shoe bottomsan'd is illustrated herein by Way of example as embodied" in a shoe repair press for cement attaching half soles` to the foreparts of shoe bottoms. y

Objects of the invention are to provide an improved shoe press of the type referred to which will be adapted 'to apply Yand sustain relatively heavy pressure against the shoe, will vbe ysimple in construction, economical to operate and yet will be capable rof operating as fast andy eiiiciently as the more complicated and expensive shoe presses in use today. l y Te the attainment 0f these epdatbe inveiitieil provides,y as herein illustrated, an improved shoe press having, Yin combination, a shoe `support, a 'pressure applying rrierriberZ ,arid mearisier efleeting relative movement between the support and the pressure appli/iria. member te appli' iiiitial pressure to a shoe in the press, After i. initial pressure has been applied. thevpress is y provided with further means ier applying additional pres- Sllie te theellee .and fer. libidine er mairitairiips this pressure as long as may be desired. Moreover, in accordance Witha feature of the invention, the additional pressure may be increased as much as. may be. desired' or as mai? be required ier the partielilar tvpe 0f lShoe beine` Operated upon, therebyinsuring a satisfactory' attachment o f the sole t0, the. s'hoebo'ttom. e y Y n As herein illustrated, the shoe support preferably comprises a vleldabie pad mounted in a pad. box of usual oonstruction supported on astationaryV base portion of the press. The pressure appli/me member comprises ari. abutment provided with Work engaging portionsI adapted to engage the forepart of the shoe and top Oi, the heel portion of the last in the shoe, this abutment being adjustably mounted on a heightwise movable member whereby the abutrreilt may be moved into and out of engagement with the shoe, the heightwise movable member being normally urged into its initial orinoperative position by resilient means.` Means is provided for moving the pressure applying member or abutment against the shoeon the support to apply initial pressure to the shoe, this means preferably being treadle operated.r

For applying additional. pressure to the shoe, the press is providedfwith an operator controlled intermittent grip device which, as herein illustrated, is adaptedrto act upon theheightwise movable member and through it to cause the Pressure applying membery te apply additional pressure to the shoe.

located. in anoperateclpesitie v The illustrated, allee press eemprisesa manoir-14 ary base or table l0 upon which is mounted a frame l2 provided with a plurality of upstanding posts I4 having secured to their upper ends a supporting plate or casting i6. Mounted in the lower portion of the frame I2 are stationary shoe supports I8 in the forni of pad boxes in which are mounted yielding pads 20 which, as illustrated in Figs. l and 2, preferably comprise hollow bags or bladders filled with fluid such as water, and having upper surfaces arranged to support a sole A and a shoe B, the sole being illustrated herein as a half sole adapted to be attached by cement to the forepart of the shoe. The machine is illustrated as a duplex or twostation machine capable of handling right and left shoes but since the operating instrumentalities of both stations are substantially the same in construction and operation, only the station which operates on the left shoe, illustrated at the left in Fig. l, will be described in detail herein.

Secured by screws to the upper side of the plate I6 is a hollow casing 22. Extending through this casing is a heightwise movable shaft 24, the lower end of which is provided with a shoulder 23 (Fig. 3) and a narrow ear 25, the latter carrying a transverse pin 26 upon which is pivoted a coupling 28 provided with a T-shaped guideway 30. Adjustably mounted in the guideway 33 is a pressure applying member 32 which, as illustrated in Fig. 2, is provided at its forward or right-hand end with an abutment 34 arranged to engage the forepart of the shoe B, the member 32 having an offset inner portion 36 provided with a horizontal lower surface 38 adapted to engage the top of the heel portion of a last L in the shoe.

The shaft 24 is normally urged upwardly into an inoperative position by a spring 40 which surrounds a reduced upper portion 42 of the shaft and is confined thereon by a washer 44 and nut 46, the lower end of the spring engaging the upper end of the casing 22. The upper portion of the shaft 24 and the spring 4B are enclosed by a cylindrical housing 48 secured by screws to the casing 22. The upper or inoperative position of the shaft 24 is determined by the engagement of a collar 50 secured to its lower end with the lower surface of the casing 22, as shown in Fig. 3. The collar 50 is provided with a laterally extending arm 52 (Figs. 1 and 2) to which is secured a treadle rod 54 which extends downwardly to a treadle 55 whereby the shaft 24 may be moved downwardly to bring the pressure applying member 32 into engagement with the shoe B and last L, release of the treadle permitting the spring 40 to return the shaft and member 32 into their elevated positions with the collar 50 engaging the casing 22. Depression of the treadle 55, therefore, moves the pressure applying member 32 into engagement with the last and shoe and forces the shoe and sole against the shoe support 2D to apply initial pressure to the shoe.

The shaft 24 is maintained in its lowered position to hold the pressure by mechanism illustrated in Figs. 3 to 5, inclusive. This mechanism coinprises an intermittent grip device which not only holds the initial pressure applied by depression of the treadle 55, but operates through the movable shaft 24 to cause additional pressure to be applied to the shoe and also to hold this additional pressure until the grip device is actuated to release the pressure applying mechanism and relieve the pressure on the shoe.

The casing 22 has an inwardly projecting horizontal portion 56 provided with a U-shaped opening which straddles the shaft 24. Mounted above the portion 56 are a plurality of superimposed gripping members or pinch plates 58 provided with holes slightly larger in diameter than the shaft 24 and through which the shaft passes, the leit-hand ends of the pinch plates, as viewed in Fig. extending into an opening tu in the casing which connues these ends against heightwise movement but permits limited pivotal or swinging movement or' the plates about centers located at or adjacent to the opening. A spring 52, surrounding the shaft 24 and seated ih a recess in the portion 5u' ol the casing, normally urges the pinch plates upwardly and thus tilts them at an angle, as shown in Fig. 3, suiiiciehtly to cause the plates to grip the sha'it 24 and thereby prevent any movement of the shaft in an upward direction away from the support or pad 2li while the plates are tilted, the tilted plates, however, permitting movement of the shaft in a downward or pressure applying direction under ioice suincieiit to overcome the spring 4d. The pinch plates 58, thereiore, constitute in effect detents lor gripping the shaft 24 and locking it against upward movement until the plates are released irom the shaft, thereby holding the initial pressure applied to the shoe by depression oi` the treadle Located below the horizontal portion 56 of the casing is a plurality oi' superimposed pinch plates till provided with alined holes slightly larger than the diameter oi' the shaft 24 and through which the shaft passes, these plates being normally urged upwardly into a horizontal position against the portion 5u' by a spring te surrounding the shaft and extending between the plates and the bottom of the casing, the shaft passing Ireely through the holes in the plates when the latter are located in a horizontal position, as shown in Fig. 3. When the pinch plates (i4 are tilted into an angular position, however, they will grip the shaft 24 similarly to the upper plates 58 and will force the shaft to move bodily with the plates as long as the latter reiiiain in a tilted position.

'i ne plates at are tilted to grip the shaft Z4 and move it downwardly to cause the pressure applying member 32 to apply further pressure to the shoe on 'the support 2U, that is, pressure in addition to the initial pressure applied by depression of the treadle 55. The casing 22 is provided with a horizontal guideway 68 (Figs. l and 2) in which is mounted a bracket l having a boss l2 thereon provided with a horizontal bore 73 (Fig. 4) in which is rotatably mounted by means ol needle bearings I4 a short horizontal shaft i5. The shaft "i3 has a rectangular outei portion i8 upon which is mounted a long oscillatable actuating member or handle SB which is maintained on the rectangular portion by a nut 82 threaded on a reduced end 84 of the shaft.

An inner portion 86 of the shaft 76 is enlarged in diameter, as illustrated in Fig. 4, and is provided at one side with a wide vertical slot 58 and at an opposite side with a second vertical slot 90 somewhat narrower than the slot 88. The slot 90 breaks into the wider slot 88 below the axis of the shaft, as viewed in Fig. 3, to leave a substantially rectangular intermediate or bridge portion 92 extending between the portions of the shaft at opposite sides of the two slots. Mounted between the opposite sides or ears of the portion 86 formed by the slot 88 is a horizontal pin 94 which, as shown in Figs. 3 to 5, inclusive, overlies and engages laterally projecting arms formed on the right-hand sides of the lower pinch plates 64. Accordingly, when the actuating member or handle 80 is oscillated in a counter-clockwise direction, as viewed in Fig. 3, the pin 94 will tilt the 3.
